Summary of the invention
The present invention designs a kind of novel circular polarisation and double-circle polarization cylinder dragon in view of above-mentioned technical background and use demand
Primary lens antenna.Novel circular polarisation and double-circle polarization cylinder Luneberg lens antenna of the invention is set based on dielectric-slab waveguide structure
Meter.In dielectric-slab waveguide, the transmission characteristic of the TE ripple and TM ripple of even mould is respectively as shown in formula (1), formula (2):
Wherein h is propagation constant of the electromagnetic wave along dielectric-slab waveguide normal direction, and β is transmission of the electromagnetic wave along dielectric-slab waveguide, P
For the attenuation constant on dielectric-slab waveguide boundary.
Since dielectric-slab waveguide is prefect dielectric structure, relative to parallel-plate waveguide, dielectric-slab waveguide can be realized TEO and
It is transmitted while TMO wave.This transmission characteristic based on dielectric-slab waveguide utilizes a linear polarization feed antenna, polarization side
To being axially in 45 ° of angles with cylindrical di plate lens, the TEO wave and TMO wave of constant amplitude have been motivated simultaneously in dielectric-slab lens.By
Formula (1) and formula (2) are as can be seen that the propagation constant of TEO wave and TMO wave is different in dielectric-slab waveguide, by changing Jie
The thickness distribution and size of scutum lens, can realize wave beam focus needed for index distribution while, realize TEO wave and
TMO wave has 90 ° of phase difference in emergent medium plate lens.Cylinder Luneberg lens antenna of the invention is exactly according to above-mentioned original
Reason is to realize circular polarisation.When needing to realize double-circle polarization, only above-mentioned linear polarization feed need to be replaced with dual-linear polarization feed,
Two polarization direction is mutually perpendicular to, and is axially in 45 ° of angles with cylindrical di plate lens.
Present invention innovative point most outstanding is the transmission characteristic that TEO and TMO wave can be supported to coexist using dielectric-slab waveguide,
By adjusting the thickness distribution and size of suitable dielectric-slab waveguide lens, the water for dexterously having motivated 45 ° of linear polarization feeds
The TMO wave for putting down polarized TEO wave and vertical polarization is realizing that order generates therebetween while being converted into plane wave by cylindrical wave
Phase quadrature, to realize circular polarisation.
Another protrusion innovative point of the invention is only replace the feed of above-mentioned circular polarisation Luneberg lens antenna
Double-circle polarization can be realized in the case where not changing dielectric-slab lens component for dual-linear polarization feed, can effectively improve
The reusable rate of design.
Since novel circular polarisation of the invention and double-circle polarization cylinder Luneberg lens antenna have the structure of rotational symmetry special
Sign, thus the present invention is equally applicable in the usage scenario of azimuth plane multi-beam surface sweeping.At this point, only need to be along cylindrical di board waveguide
Lens circumference arranges arc feed battle array, according to the beam angle that single feed generates, adjusts spacing between arc feed array element
Realize the uninterrupted beam scanning of azimuth plane.
Meanwhile the dielectric-slab waveguide lens component in the present invention, it can be completely by the way of machining, by one piece of cylinder
Shape dielectric-slab turnning and milling has the advantages of the processing is simple at the section shape of certain rotational symmetry.Due to cylinder dragon of the invention
Primary lens are prefect dielectric structure, eliminate the metal parallel plate of traditional cylinder Luneberg lens antenna, therefore, the present invention realizes day
The lightweight of line.
Embodiments of the present invention are that the electromagnetic wave that 45 ° of linear polarization feeds or double 45 ° of linear polarization feeds radiate enters medium
In board waveguide lens, using the transmission characteristic of dielectric-slab waveguide, after electromagnetic wave passes through lens, while forming narrow beam,
Realize circular polarisation or double-circle polarization.
